swift println() not showing autocomplete options w

问题:

When I am trying to print using println() function it is not showing autocomplete parameter list in swift. Is there any problem in my xcode?

回答1:

Delete user/Library/Developer/Xcode/DeriveData and delete the data of folder(Derive data) and restart Xcode. Should work. If doesn't, restart mac after doing this.

Hi I found the reason for this.... As Dhruv mentioned, it only accepts string argument. So we need to convert object to string inline println() function.

For example:

we have integer defined as var age:Int = 24

then we can print this as

println("\(age)")

In this case we will get autocomplete option. On other hand println(age) will print same result as above.
