This year iPhone and iPad are on their way to become the biggest selling gadgets which rely on the iOS operating system for their functionality. There is a high demand for iOS Development as most of the businesses are moving towards developing iOS apps for their business.

Hundreds of iOS apps are designed, developed and released. Thousands of apps are updated on a regular basis. Apple play store is overflowing with all kinds of apps covering almost all industries. The apps are developed in high standards to match Apples Brand. Developers have to face a number of challenges in the form of bugs and issues. Sometimes they have to use all of their knowledge and experience to solve some issues.

As an iOS development company, we are discussing some issues related to Layout, Storyboard and Invalid Bundle.

Issue 1: Layout

Normally, iOS development is done by selecting one of the layouts because the programming has to be done as per the resolution of Apple devices. We face some issues when we shift from one version to another, for example from Xcode7 to Xcode8.As a result, the layout gets distorted.

Solution:

• Open your storyboard in Xcode 8.

• Choose initial device view.

• Make changes as you would perform normally.

• After changes are done, choose storyboard -> File Inspector -> Opens in -> Select ‘Xcode 7.x’.

• Select ‘Save and Close’ when prompted.

• Your storyboard changes will be saved, and your storyboard will function as it did pre-Xcode8.

Issue 2: Springboard fails to Launch Application

Sometimes due to some fatal issues the springboard is unable to launch the application due to the error:0

Solution:

• Make sure your Simulator is active.

• Open menu (give in the below image).

• Click “Reset Content and Settings”.

• It will ask – if you really want to reset your setting, Select Yes.

• The app is then run from Xcode, not to show the error again.

Issue 3: Xcode ERROR ITMS-90474

Xcode ERROR ITMS-90474: “Invalid Bundle”, can’t submit App file (IPA file) to Apple

“Bundle Invalid. iPad Multitasking support requires there orientations: ‘UIInterfaceOrientationPortrait,UIIinterfaceOrientationPortraitUpsideDown,UIInterfaceOrientationLandscapeLeft,UIInterfaceOrientationLandscapeRight’. Found ‘UIInterfaceOrientationPortrait’ in bundle.

Solution:

To resolve this issue, you need to click on “Requires Full Screen” checkbox under Deployment Info in Project’s General tab.

Or You can also add Key value pair – UIRequiresFullScreen: YES, in Info. List file of the Xcode Project.

Despite of the above-mentioned issues, some precautions which must be taken care of during Ios App Development are:

• Check the processing, it should be connected.

• Run UI related code with main thread.

• Check concurrency and multithreading

• Know the working of Mutable objects

• Developers must know the working of NSDictionary to develop accurate iOS app.

• Use hardcoded values

• Avoid using NSLog for logging
