I have been dabbling with XCode and Swift for the past few days and thought of sharing some tips and tricks i learned.

###How to create a rounded corner button

There is no direct way to set corner radius for your button in xcode attribute inspector. So what you should do is, create a user defined run time attribute for corner radius.

Select your button, Go to Identity Inspector, there you will see a section called User Defined Runtime Attributes. Click on the + button to add a new record and enter the following values

Key Path : layer.cornerRadius
Type     : Number
Value    : 8 //or whatever value you want for your corner radius.

Settings

And your output will be

Output

Cheers !
