Xcode swift indexing forever

Question

I\'m currently developing an iOS app using swift and Xcode 6 (Beta 3).

Everything went fine so far but now as my project grows, Xcode suddenly began indexing and it

Answer 1

It's XCode bug. Problem caused with concatenation in one line:

var value = "some text" // it can be String or Array
value = value + value1 + value2 + value3 + value4 + value5 + value6 // etc

This correction fixes this bug:

var value = "some text"
value += value1
value += value2
value += value3
value += value4
value += value5
value += value6
