let intervals = [[1,1],[2,2],[3,3]]
I would like to store this intervals variables into CloudKit
as String in the same form as a print
output eg:
print(interval)
output = [[1,1],[2,2],[3,3]]
How can this be achieved? All the solutions from SO and googling only led me to doing a join whereby the arrays would be lost eg: [1,1,2,2,3,3]
CodePudding user response:
You can try
let intervals = [[1,1],[2,2],[3,3]]
let res = "[\(intervals.map { "[\($0.first!),\($0.last!)]" }.joined(separator: ","))]"
print(res)
OR
let res = String(data: try! JSONEncoder().encode(intervals), encoding: .utf8)!
OR
let res = String(describing: intervals)
