There are no errors and warnings in the code. I push the button Build - takes off from Xcode. This is a non-permanent problem. With the same code it may or may not fly out. Xcode reinstalled, is the latest version.
Am I alone with this problem or did someone come across this? Already can not stand the nerves tolerate regular crashes. You have to restart 10 times to find out if the error is fixed or not.
