Illegal configuration: compiling IB documents for versions earlier than iOS 7 is no longer supported

Question

I recently upgraded to Xcode 9 . When I create the application, it says “illegal configuration” for some storyboards in my pod files. I tried to recreate the storyboard files, but this does not help.

Answer 1

Xcode 9 does not support storyboards created for iOS version less than 7.

Try changing the Lines for in File Inspector to a higher version, then clean and create.

See screenshot

Edit: Important information from @ user435779 below: Restart Xcode if the errors persist.

Answer 2

Just set the deployment target of 8.0 + to General to fix this problem. No need to go through every xib file.

Answer 3

Since the storyboard in Xcode 9 will not support below iOS 7.0, you need to update the iOS version in the File Inspector .

Hope this works !!!

Answer 4

I tried both ways - on Xcode 9.3 (9E145)

For each XIB, I added the following goal.

On Target → General → Deploy Info-> Change Target

We cleaned the project and built it into the device again. It worked!

Answer 5

My case was different, I followed all the above solution, but did not receive a successful build, so I read the error with focus and went to the file manually. Open the .Xib file and change its development goal to iOS 10 and later.

and yes .. his work is good
