What happens in Dropbox API for iOS (Swift) if I create a folder that already exists? - dropbox

Question

The first time I do it, I want the folder created.
The next time, should I check if folder already exists, or just do the create folder and assume nothing happens?

You can do this either way:
Check if the folder exists before attempting to create it:
client.files.getMetadata(path: folderPath).response { response, error in
if let _ = response {
print("Something already exists at path.")
} else if let error = error {
switch error {
case .routeError(let boxed, _, _, _):
switch boxed.unboxed as Files.GetMetadataError {
case .path(let lookupError):
switch lookupError {
case .notFound:
print("Nothing was found at this path. Attempting to create folder...")
client.files.createFolderV2(path: folderPath).response { response, error in
if let response = response {
print("Created folder:")
print(response)
} else if let error = error {
print("Error creating folder: ")
print(error)
}
}
default:
print("Some other error occurred.")
// handle accordingly...
}
}
default:
print("Some other error occurred.")
// handle accordingly...
}
}
}
Always attempt to create the folder, and handle the error that occurs if it already exists:
client.files.createFolderV2(path: folderPath).response { response, error in
if let response = response {
print("Created folder:")
print(response)
} else if let error = error {
print("Error creating folder: ")
print(error)
// handle accordingly...
}
}
