Swift : How to get the string before a certain character?
You can do the same with rangeOfString()
provided by String
class
let string = "Hello Swift"
if let range = string.rangeOfString("Swift") {
let firstPart = string[string.startIndex..<range.startIndex]
print(firstPart) // print Hello
}
You can also achieve it with your method substringToIndex()
let string = "Hello Swift"
if let range = string.rangeOfString("Swift") {
firstPart = string.substringToIndex(range.startIndex)
print(firstPart) // print Hello
}
Swift 3 UPDATE:
let string = "Hello Swift"
if let range = string.range(of: "Swift") {
let firstPart = string[string.startIndex..<range.lowerBound]
print(firstPart) // print Hello
}
Hope this can help you ;)
Use componentsSeparatedByString() as shown below:
var delimiter = " "
var newstr = "token0 token1 token2 token3"
var token = newstr.components(separatedBy: delimiter)
print (token[0])
Or to use your specific case:
var delimiter = " token1"
var newstr = "token0 token1 token2 token3"
var token = newstr.components(separatedBy: delimiter)
print (token[0])
Following up on Syed Tariq's answer: If you only want the string before the delimiter (otherwise, you receive an array [String]):
var token = newstr.components(separatedBy: delimiter).first
