Use the swift command to compile and run swift files.
Notes on swift.
- Swift strings are weird and cannot natively be indexed to get a char.
- uses
.countinstead of JS.length - Cannot do a boolean check on a number, must include comparitor e.g
myNum != 0. - Can make use of
for inloops. - String concat is done with "(variable)"
- We can specify multiple constructir sigs, general is:
init() {}but we could also doinit(withPairs pairs: [Any]) {}for instance. - The
Characterclass has a property called unicodeScalars that return an array of unicode numerical values. to get the unicode val return the first in that array. - arrays have .sort and .filter functions availabel to them, they accept the { $0, $1... syntax } e.g.
myArr.sort {
return $0 > $1
}
- Cannot use the typical for(i = ...) loop syntax, must use for in and if you want to enumerate the array you have to do
for (index, item) in arr.enumerated()
