Kotlin Solution

Use the built-in Kotlin substringBefore function (Documentation):

var string = "So much text - no - more"
string = string.substringBefore(" - ") // "So much text"

It also has an optional second param, which is the return value if the delimiter is not found. The default value is the original string

string.substringBefore(" - ", "fail")  // "So much text"
string.substringBefore(" -- ", "fail") // "fail"
string.substringBefore(" -- ")         // "So much text - no - more"
