UITableViewAutomaticDimension not working in Xcode 6.3

阅读更多关于 UITableViewAutomaticDimension not working in Xcode 6.3

问题 I updated my Xcode to 6.3 along with Swift 1.2, and I made the transition. Everything works except dynamic row height for table view. I have those on 3 completely different table views, so it probably isn't something else influencing the bug. I set all of the table views to: tableView.rowHeight = UITableViewAutomaticDimension and all of my xib files are properly constrained. Any ideas? 回答1: I simply added UITableViewAutomaticDimension to estimatedrowforindexpath as well. You can see how it

Attempting to run my project in the iOS simulator, I get a launch code error '0'. Checking the console logs in CoreSimulator.log I found the .app executable "has missing or invalid CFBundleExecutable in its Info.plist" . I'm not sure how to deal with this issue.

Since XCode 6.3 -> Nib could not be loaded [duplicate]

阅读更多关于 Since XCode 6.3 -> Nib could not be loaded [duplicate]

This question already has an answer here: Xcode 6.3: Could not load NIB in bundle 4 answers I updated my XCode from 6.2 to 6.3 today. I adapted all the swift changes, but when I run the application, I get errors for every NIB I try to load that has ~ipad or ~iphone . (NIB could not be loaded) Nibs that don't have that device modifier load as usual. If I remove the ~iphone or ~ipad , the nib can be found again, but obviously thats no solution, because it's an Universal App. Same goes for every other file type, that I try to load via code e.g. storyboards. hypercrypt Seems to be related to size

String if let firstname = firstName { // Continue } else { // Handling the error. } 来源： https://stackoverflow
