问题 I have created a standard outlet for a view that will hold different information based on the button selected on the previous screen. @IBOutlet weak var labelView: UIView! It shows it is connected in both the story board view and on the code itself, however, every time I get to any reference to the labelView such as: if detail.description == "About" { labelView.backgroundColor = UIColor.red } Then the app crashes out with: fatal error: unexpectedly found nil while unwrapping an Optional value

XCode 8.2.1 Cannot add folder reference

由 主宰稳场 提交于 2019-12-10 18:05:00
问题 My XCode 8.2.1 doesn't let me add a folder reference. What I have tried: I make a right click on the folder called "Unity", then I click on "Add files to Project...", under options I check "Create folder references". My folder is added as a red file instead of a blue folder how it would be normally. I tried changing the 'type' of the file to 'folder' under "Identity and Type", then it becomes a light blue folder, but there are no files inside and I can't seem to put them inside in any way,

Use Legacy Swift Language Version - Xcode 8.2

问题 After updating to Xcode 8.2 the compiler throws one error for my App target: “Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift.

Xcode 8.2 Code Completion Not Working

由 帅比萌擦擦* 提交于 2019-11-28 05:11:46
For some reason, in Xcode 8.2 my code completion has stopped working. I have cleaned my product, restarted Xcode, restarted my computer, and deleted the derived data, and still no luck. I have submitted this to Apple Support. Has anyone run into this before and been able to fix it? Code completion also stopped working for me in Xcode 8.2.1, and no amount of clean-up, derived data throwaway or restart fixed it. After a while, I realized code completion was only broken within the extension scope I was working on. If typed manually, the code would be correctly highlighted and would compile fine,
