This proposal consists in adding a functionally that I find useful in VB .net, that lets you set a default return value of a function at the begging rather than at the end
current: func myComplexOperation() -> Int { //Some long complex code that might return some value //Default return at the very end return 0 } proposal: func myComplexOperation() -> Int { //set the default return at the begging using the ‘default’ keyword or some other keyword default 0 //Some long complex code that might return a value //if the end of the function is reached, return the default } The other alternative will be to allow naming the return value proposal2: func myComplexOperation() -> result:Int { //set the default return at the begging using the output variable name result = 0 //Some long complex code that might return some value } Another alternative will be to set the default value directly like and optional parameter proposal3: func myComplexOperation() -> Int = 0 { //Some long complex code that might return some value } In all of the cases the compiler will check that a default return is set before exiting the function It could be some combination of the 3 proposals Thanks _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
