contentView is broken. It can be also fixed in awakeFromNib ObjC: – (void)awakeFromNib { [super awakeFromNib]; self.contentView.frame = self.bounds; self.contentView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; } Swift3: override func awakeFromNib() { super.awakeFromNib() self.contentView.frame = self.bounds self.contentView.autoresizingMask = [.flexibleWidth, .flexibleHeight] }
I was running into the same issue and couldn’t get my project to import swift into obj-c classes. Using Xcode 6, (should work for Xcode 6+) and was able to do it in this way…. Any class that you need to access in the .h file needs to be a forward declaration like this @class … Read more
I had the same problem, also in my XCTestCase files, but not in the regular project files. To get rid of the: Use of unresolved identifier ‘PrimeNumberModel’ I needed to import the base module in the test file.
