Convert an array of string to an array of images - arrays

Question

I have an array of string which to convert to an array of images.
var inviteStatus = [Any]()
inviteStatus = ["accepted", "accepted", "pending", "pending"]
When the invite status is "accepted", I want it to be replaced with an image at that index. The desired result is this:
inviteStatus = [UIImage(named: "accepted.png"), UIImage(named: "accepted.png"), UIImage(named: "pending.png"),, UIImage(named: "pending.png")]
I tried with this following code but it's not working:
for (index, str) in self.arrayInviteStatus.enumerated() {
self.arrayInviteStatus[index] = str.replacingOccurrences(of: "accepted", with: UIImage(name: "accepted.png"))
self.arrayInviteStatus[index] = str.replacingOccurrences(of: "pending", with: UIImage(name: "pending"))
}
Thank you for your help.

Answer 1

Use map
let inviteStatusImages = inviteStatus.map{ UIImage(named: $0+".png") }
You are discouraged from using [Any]. Better use two separate arrays with distinct types.

Answer 2

I think map is definitely the way to go, but maybe consider using an enum, so you get a type safe way to distinguish between the two cases:
enum InviteStatus {
case accepted
case pending
}
Now you could have an Array of InviteStatus and combine map with pattern matching:
let inviteStatus: [InviteStatus] = [.accepted, .accepted, .pending, .pending]
func statusToImage(status: InviteStatus) -> UIImage {
switch status {
case let .accepted: return UIImage(named: "accepted.png")
case let .pending: return UIImage(named: "pending.png")
}
}
let imageArray = inviteStatus.map(statusToImage)
What this gives you is the ability to easily refactor without losing type safety. E.g. if you want to add another status case in the future like "declined", or something similar, you can add it to your enum and the switch-case pattern match will tell you at compile time that you'll have to add another case to it.

Answer 3

you can do like this
var inviteStatus: [String] = []
inviteStatus = ["accepted", "accepted", "pending", "pending"]
var imgArray: [UIImage] = []
imageArray = inviteStatus.map { UIImage(named: "\($0).png") }

Answer 4

You can try to create an integrate array and then pass the variables to the original array
var inviteStatus = [Any]()
inviteStatus = ["accepted", "accepted", "pending", "pending"]
//inviteStatus = [UIImage(named: "accepted.png"), UIImage(named: "accepted.png"), UIImage(named: "pending.png"),, UIImage(named: "pending.png")]
var newArray = [Any]()
for invStat in inviteStatus {
newArray.append(UIImage(named: "\(invStat).png"))
}
inviteStatus.removeAll()
for na in newArray{
inviteStatus.append(na)
}
