AssetQuery

Convenience initializer for creating an AssetQuery with the “mimetype_group” parameter specified. Example usage:

let query = AssetQuery.where(mimetypeGroup: .image)

Instance method for mutating the query further to specify the mimetype group when querying assets.

Static method for creating a new AssetQuery with a select operation: an operation in which only the fields specified in the fieldNames parameter will be returned in the JSON response. This variation for initialization guarantees correct query contruction by utilizing the typesafe Asset.FieldKeys. The “sys” dictionary is always requested by the SDK.

Example usage:

let query = AssetQuery.select(fieldsNamed: [.file])
client.fetchArray(of: Asset.self, matching: query) { (result: Result<ArrayResponse<Asset>>) in
    switch result {
    case .success(let arrayResponse):
        let assets = arrayResponse.items
        // Do stuff with assets.
    case .failure(let error):
        print(error)
    }
}
