Xcode 10

The newly released Xcode build the system with Xcode 9 by Apple is in the preview mode. The advanced features were not active during that time. The activated Xcode 10 features by default have some issues in the iOS projects since Apple is aware of these, they have separately issued new build system. They have also mentioned possible solutions to tackle those issues.

We are here to highlight the top 5 issues iOS developers might face and they might not be covered in the recent release notes, e.g. Xcode 10 system requirements and the system behaviour of new build with third-party tools.

Xcode 10 Features: The Newly Build System

You can now activate new build settings from Xcode Files-> Project/Workspace Settings with this toggling between legacy and new build system becomes easy. Additionally, if you are building an iOS project right from the command line using the Xcode build then it is required to pass additional parameter such as UseModernBuildSystem=YES.
The latest build system is called as the xcbuild. The new build system elevates the overall swift build by running the targets and its build phases side by side. Once it is activated you will face both its benefits and issues in regard to the new build system in your project. Here we will try to identify the issue and get solutions immediately.

1. The Info.Plist

When an iOS project is built using the new build system you will face several issues regarding the info.plist files. Here are the few things you need to keep in mind regarding New Build System and info-plist files.

  • Make sure there is no duplicate plist file in the copy bundle resources in the build phase of any target. Otherwise you will not be able to create an app with the new build system. Additionally, the files copied multiple times will hamper the functioning.
  • The new build system functions on various precedence of running info-plist step within the clean and incremental builds. In the clean build, you will find that the info.plist steps after processing assets, whereas the incremental build runs before signing.
  • If there only info.plist value and does not have the Xcode reference folders then you will face an Xcode build system failure.

2. The CocoaPods

CocoaPods bring some issues for the iOS projects.

  • With CocoaPods development pods will not be updated unless a clean build is performed. The embedded pods are not executed successfully.
  • Some of the Cocoapods build phase script doesn’t run reliably as you may see disbursement in its behaviour and you might not be able to archive the app.

Hence, this makes it clear that cocoapods and the new build system don’t get along well together.

3. Running the Script Phase

The new build system is full of flaws with the Run Script Phase started giving false results. But this too comes with a good reason.
The new Xcode 10 features have a lot of improvement in the Run Script Phase. However, it requires you to help build processes with the help of feeding files for the run script phase. You will have to specify the input files to the run script phase, this is important to determine whether the script needs to be run or not.
If Xcode build system runs parallel commands then the input for the run script phase will not be generated, this fails the build system as it gets confused. However, providing the input files to run scripts is advisable as when the inputs grow in number it gives a way to specify all the input files in the .xcfilelist format. Hence it is recommended to add the files to avoid running this phase for all the other incremental builds whenever it is not required.

4. Clean Build Folder Action

With the new build system, a clean build folder has been introduced. This introduction eliminates all the derived data of the iOS application causing the cleaner builds right from scratch. This step means if you are using cocoapods all the frameworks will be rebuilt from the scratch and you will face a delay in developing an iOS project. There may be Xcode indexing issues as well.
The new build system by Apple is introduced to improve the performance, reliability, and stability of the Swift build. This system is designed to capture the configuration errors early in the application development phase. In Xcode 10 mascos version so you don’t have a choice and you will have to update the build process to adapt to the new build system. This scenario demands a lot of configuration enhancements in the app.


There are a number of iOS developers might be using .xcconfig files to keep the Xcode build settings at one place for the appropriate goals. There are some queries that conditional variable assignment in the xcconfig files might not work as wanted, because of the build failures. To ensure your xcconfig files, Apple suggested running following command.

defaults write EnableCompatibilityWarningsForXCBuildTransition -bool YES

If this command displays any errors or warnings, we must have to solve it to get stable builds.

Moving Forward

The recent Xcode 10 release date was September 17, 2018. Let us know have you tried the Xcode code dark mode yet or migrated to the new build system? If yes, what are your experiences? If you wish to share your views or get an issue resolved, get in touch with us without any hesitation.

blockchain technology in healthcare

Blockchain was created in the year 2008 by Satoshi Nakamoto, a pseudonymous person and was utilized as a major element of the digital currency, ‘bitcoin’.

What is Blockchain Technology?

The blockchain is the technology that took the industry by storm by its groundbreaking work in data handling and its exchange. Its enormous success across diverse industries has left even the healthcare space to fluster with queries. People are considering it the ‘solution to interoperability,’ and the technology that can resolve healthcare’s alarming issues,’- however, if the perplexity looms, blockchain will take more time than the required to make a difference in the healthcare space.

Benefits of Using Blockchain Technology in Healthcare

  • Single, longitudinal patient records
  • Longitudinal patient records can better compile episodes, disease registries and lab outcomes. The treatments can be attained via blockchain, comprising inpatient, ambulatory and wearable data assisting enablers, also coming up with improved ways of delivering healthcare services.

  • Master the patient indices
  • Time and again when dealing with healthcare information and data, records get incompatible or turn duplicated. Even diverse EHRs have altered schema for each single field – coming up with ways of inflowing and influencing the simplest of required data sets.

    With blockchain, the intact data set is being hashed to a required ledger, and not mere the primary key. The user would look for the address – there can be manifold addresses and numerous keys, but they will all capitulate to a solitary patient recognition.

  • Claims adjudication
  • Since blockchain operates on a validation-based exchange, the claims can be automatedly verified where the network accepts upon the way a contract is carried out. Even since there is no centralized authority, there would be lesser errors and frauds.

  • Supply chain management
  • Blockchain contracts can help healthcare organizations in tracking supply-demand cycles via its complete lifecycle – how is the transaction being executed, whether the contract is flourishing, or if there are any further delays.

  • Interoperability
  • Interoperability, the assurance of blockchain, can be comprehended by the utilization of APIs to make EHR interoperability and data storage a steadfast procedure. With a blockchain network being shared with authorized services providers in a secure and uniform way that would get rid of the cost and burden connected with data reconciliation.

    Other than these benefits, blockchain can even transform drug supply management, the revenue cycle management, required clinical trials and put off the frauds.

How to Implement Blockchain Technology in Healthcare with its Applications

Having explored the significance of blockchain technology in the healthcare sector along with the alterations that it could bring, here are some of the use cases that use the latent of the technology and could make the healthcare industry easier to get to, secure and trustworthy.

  • Managing the Population Health Data
  • Population health data refers to the medical data of a specific demographic. For instance, it may be health risk data for women suffering from thyroid in the group of 25 to 40 years. To comprehend the risks across a diverse population, the data is typically offered in an anonymized form and no names are publicized in these cases.

    Blockchain provides a consistent solution to this precise challenge. When applied accurately, blockchain will allow enhanced Security, data sharing, interoperability, data integrity and Real-time modernization with required access.

    Utilizing blockchain technology can enable people to contribute in population health studies to and monetize their data in the medium of tokens. Moreover, superior data and sharing of population health data can perk up healthcare delivery transversely via diverse populations. With more data sets, the use of new technologies like ML and AI would be possible which will lead to discovering extensive risks of population health.

  • Securing the Healthcare Setups
  • The present healthcare system and organizations work via one single central database. This database is handled by one entity in the organization. In this way, the point of failure comes to one sole point. In such scenarios, if a hacker or an anti-social component attacks the system, the concerned user can way in the on the whole database and would put the patients as well as the organization in risk.

    Blockchain can be used to safeguard the internal infrastructure of a setup. A large-sized organization with numerous independent actors having diverse levels of a way in on a blockchain ledger along with the encryption embedded on the blocks will protect organizations from outside attacks. If a blockchain network is directed precisely in a healthcare organization, it would avert such ransom attacks and other problems such as data corruption and hardware failures.

  • Making Patient Payments via Cryptocurrencies
  • Another tempting application of Blockchain in healthcare is the utilization of cryptocurrencies as payments instead of cash or fiat money. The cash healthcare practices are in occurrence however, the health care expenses are not defined as such.

    By having blockchain systems and applications implemented the possibility of offering the precise solutions and eliminating frauds has amplified. Bill processing automation removes the 3rd parties from the complex chain and has reduced the overall administrative costs. In addition, when larger institutions will adopt payment processing through cryptocurrencies, a major reallocation would take place. Each penny paid to the Medicare would be monitored and make sure that no frauds are made during the procedure.

  • The Drug Traceability
  • Counterfeiting of drugs along with forged drugs in the supply chain leads to a big loss of billions of dollars every year. As per the Health Research Funding Organization (HRFO), report, 10 % to 30 % of drugs in developing nations are not original.

    The key feature of blockchain technology that can be applied in medicine traceability is its precise security. With every new transaction which are added to a block will be irreversible as well as time stamped. This will make it trouble-free to trail a product and make sure that the data in the block cannot be distorted.

    Likewise, the attribute of data transparency in a blockchain system can lend a hand to find the entire path of origin, thus, serving in getting rid of the exchange of fake drugs.

Moving Forward

There is a rapid development of blockchain in financial applications. However, the blockchains latent for healthcare relies on how willing healthcare organizations are to build the needed technical infrastructure. The blockchain is expensive, there is some apprehension concerning its integration with the existing technology, and there surely is some critical assumption about its cultural adoption in healthcare space.
